The Larmor frequency of Xe-129 spins is temperature sensitive and can
be used to sense RF heating during CEST detection
For the production of hyperpolarized xenon we continuously improve our spin exchange optical pumping setup and gas delivery options
Efficient nanocarrier design improves the CEST effect, the targeting specificity, and the biocompatibility of Hyper-CEST reporters

A key compnent of novel biosensor design is the translation of
biochemically relevant targets from fluorescence detection to MRI studies
with live cell experiments
Understanding and quantifying the exchange kinetics of reversibly bound spin labels is crucial for ultra-sensitive NMR applications
